CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of U.S. Provisional Patent Application No. 60/897,983 filed Jan. 29, 2007, the entire disclosure of which is incorporated by reference.

BACKGROUND

The present disclosure relates to controlling systems of a building, such as those which provide heating, ventilation, air conditioning, fire detection, and building access and security; and more particularly to a user interface for such building automation systems.

Large commercial and institutional buildings have several systems for controlling different aspects of the building operation. A heating, ventilation and air conditioning (HVAC) system manages components which control the interior environment of the building. A security system includes devices which limit access to the building to only individuals who possess a proper access code or access device, such as a key card. A fire detection system utilizes heat and smoke detectors located throughout the building to sense the occurrence of a fire and produce a warning of that event. Other systems may monitor and control lighting and other electrical loads for optimum energy conservation.

Building systems may be autonomous or networked together in an integrated system. In either case, the systems may be controlled by workstations at one or more locations within the building or at a remote location. Such workstations may be located at the manager's office, the building operating engineer's office, and/or at the security desk. When the building is part of a larger commercial or educational campus, the systems and networks for each building can be connected to a wide area communication network, the Internet, or some other network which enables control from a central campus facility management office or offsite location. Offsite communications may be accomplished with standard or proprietary wired or wireless telecommunications links.

Modern building automation systems may include a variety of user interface features that allow a user (e.g., building engineer, facility employee, manager, etc.) to view or control parameters or settings of various facility systems (e.g., HVAC, security, emergency, etc.). For example, a building automation system may include a computer application or browser interface configured to display the various hardware components of the HVAC system and the components' operating parameters. As various components or subsystems of building automation systems have become more connected and complicated, facilities management user interfaces and the systems that control the user interfaces have become complicated.

In many instances, a user of a typical building automation system must have highly detailed knowledge of the hardware design of the system he or she would like to control before being able to investigate a problem or develop a solution. Furthermore, in many instances the user is not presented with natural language or intuitive control options. Rather, users are typically required to navigate detailed hierarchies of information before they are presented with a screen that allows them to change a value (e.g., a scheduling parameter, a setpoint parameter, etc.). Even if a user is presented a screen for changing a value early in the navigation experience, the method for changing a value is typically cumbersome, especially for novice users that know the outcome they would like, but not necessarily the parameter names or other system design details.

There is a need for improved graphical user interfaces for building automation systems. Furthermore, there is a need for system configured to generate a graphical user interface that presents a user with task-based or outcome focused options for controlling the building automation system and/or devices thereof. Yet further, there is a need for a system configured to provide an intuitive and easy-to-understand method and associated graphical user interfaces for temporarily overriding a schedule and/or for changing a value.

What is needed is a system and/or method that satisfies one or more of these needs or provides other advantageous features. Other features and advantages will be made apparent from the present specification. The teachings disclosed extend to those embodiments that fall within the scope of the claims, regardless of whether they accomplish one or more of the identified needs.

For example, ADS 130 may serve user interface applications. ADS 130 may also serve applications such as Java applications, messaging applications, trending applications, database applications, etc. ADS 130 may store trend data, audit trail messages, alarm messages, event messages, contact information, and/or any number of BAS-related data. Terminals may connect to ADS 130 to access the entire BAS 100 and historical data, trend data, alarm data, operator transactions, and any other data associated with BAS 100, its components, or applications. Various local devices such as printer 131 may be attached to components of BAS 100 such as ADS 130.

Various BAS configurations are possible. According to an exemplary embodiment one computing device of BAS 100 will serve as the site director for the rest of the BAS. The site director may be considered the head device or controlling device of a BAS. Depending on the scale and/or configuration of the BAS, different devices may be the site director. For example, in some large systems ADS 130 will control multiple NAEs 102 and their connected building devices (as shown in FIG. 2). In smaller or more simple systems, one NAE 102 may be the site director.

UI Server and Architecture

The site director is typically a machine and/or collection of hardware/software that includes workstation or power-user focused user interface software. According to the exemplary embodiments shown in FIGS. 3A and 3B a UI server is provided in addition to the BAS site director. The UI server is generally configured to provide intuitive graphical user interface views for less experienced users and experienced users alike.

Referring to FIG. 3A, a block diagram of a system 300 of a UI server and external site director is shown, according to an exemplary embodiment. UI server 304 may be part of BAS 100 of FIG. 2 (e.g., UI server 132 of FIG. 2). BAS device 306 may be any type of device, for example, any of the devices 102 through 126 of FIG. 2. BAS site director 302 may be ADS 130 or NAE 102 of BAS 100 shown in FIG. 2. According to one exemplary embodiment, UI server 304 and BAS site director 302 may communicate via network 320 and BAS site director 302 and BAS device 306 may communicate via network 321. Networks 320 and 321 may consist of a wired or wireless connection and may be any type of network or any number of networks. Networks 320 and 321 may be the same network, according to an exemplary embodiment.

UI server 304 is configured for communications with various client devices. For example, personal computer (PC) browser 308 and handheld browser 310 are shown communicably coupled to UI server 304. Browser 308 may be on a PC or other computing device having full screen size graphics capabilities (e.g., terminals 104 of FIG. 2), and handheld browser 310 may be on a personal digital assistant (PDA), cellular phone, or any other such device. Device browsers 308 and 310 may communicate with UI server 304 either via a wired or wireless connection.

Referring still to FIG. 6, the UI server may receive inputs from and send output to one of the browsers via the a web server. When input is received from the user, the web browser may provide further input to application server 620 of FIG. 6, which processes the input and determines a response to the input. A web server of the UI server may receive a response from the application server and use the response to generate one or more GUI elements. Application server 620 may be coupled to BAS site director 302 and data server 630. Application server may facilitate interaction between the web servers and the data stored (e.g., site director 302 and/or data server 630). When a user utilizes the GUI to make a change to a BAS item, the application server may be configured to translate input received from the user via the web server into one or more messages for the site director and/or the data server. For example, if the user utilizes the GUI to change a setpoint for a BAS controller or to temporarily override a schedule, the application server may receive the relevant input, process the input, translate the input into one or more messages for the site director and/or data store, and send the messages. The application may wait to receive a confirmation or other input from the site director before providing a confirmation back to the user via a GUI. It is important to note that any past, present, or future method for communicating queries, commands, and/or other messages may be utilized between the web server, application server, data server, and/or site director.

User Interface Look and Feel

Referring to FIG. 7, a view of a general layout for a GUI 700 that a BAS UI server may be configured to generate is shown, according to an exemplary embodiment. GUI 700 may be a UI for a PC or other device with a relatively full-sized screen. GUI 700 may be configured to accommodate various PC browser screen resolutions, according to an exemplary embodiment.

GUI 700 as shown may be the general layout for a “master” page configured to be the main or first page provided by GUI 700 to a user. The master page may provide a general layout for the various displays and functions of GUI 700 (e.g., logging out, switching between functions, etc.). General responsibilities of the main or master page of GUI 700 may include indicating date and time; indicating the current user (e.g., the username of the account currently logged in); providing access to online help, an “About” box; providing a mechanism for setting, switching, and indicating the UI function mode; limiting available function modes based on the user type and authorization; providing product and/or company information and branding; providing a layout for the user interface; and providing a mechanism for logging out a user.

Various BAS and UI system information may be provided in a variety of views or formats within the UI. The various views may provide actions such as paging, sorting, and filtering to allow users to access desired information. The views may also provide users with standard ways to access help, refresh displayed information, and return to a previous view, among other actions.

Container 701 is shown as part of the UI for the system. Container 701 generally includes selection area 704 and workspace area 706, and may be dependent upon the active function mode of the user interface. For example, in some function modes, selection area 704 may be hidden and container 701 may only include workspace area 706.

Selection area 704 is configured to contain a selection component configured to provide the user with a set of “selection mechanisms” that allow the user to choose the context and/or scope of information to be displayed in workspace area 706.

According to an exemplary embodiment, the selection mechanisms may be selection trees. Selection trees may be tree-type hierarchies derived from navigation views provided by the user interface. The user may select a tree to display, and select a “node” from within the tree to set the selection context for the workspace view within the various function modes of area 706. According to other exemplary embodiments, other tree hierarchies such as a spaces tree (e.g., a tree that defines the buildings, floors, and other spaces in a facility) may be used, or non-tree-based mechanisms may be used (e.g., a list of bookmarked items).

According to one exemplary embodiment, a selection tree (or other selection mechanism) for selection area 704 may be static for a single BAS (e.g., the selection tree may provide all building areas for a user to select). According to another exemplary embodiment, the selection tree may not be static for a single BAS. Rather, user permissions or other user and/or situational attributes may be used to determine the context of the selection tree. For example, administrators may have access to contexts not available to regular users. By way of further example, the system may automatically inspect user permissions to determine that a first selection tree should be provided to a first user and a second selection tree should be provided to a second user.

Workspace area 706 may contain workspace components related to an active function being managed by the user or displayed for the user. Workspace area 706 displays information within the user interface and also provides access to related tasks and user actions.

Tasks are operations that a user initiates in order to properly monitor, operate, maintain, and manage a facility. The view displayed for a particular function by workspace area 706 provides a user with a way to accomplish a set of tasks related to the viewed function, such as viewing a set of information, changing values, overriding schedules, or responding to alerts within the facility system and user interface system. Access to the tasks may be provided by the user interface as a textual or graphical link, menu options, or a selection list within workspace area 706. A task may be accomplished “directly” (e.g., a single mouse click or keyboard stroke) or may require user confirmation and/or input (e.g., user entries within a form). Tasks may be conditionally available based upon the authorization level of the user (e.g., administrator) and the type of information provided by workspace area 706.

Function bar 708 may be designated to display the various function buttons of the user interface. Function bar 708 may include buttons for various function modes of the facility system. For example, buttons may be provided for an alerts function mode, a summary function mode, a schedules function mode, a diagnostics function mode, and a tools function mode.

Function buttons on function bar 708 may be displayed conditionally, and may vary depending upon the type of user detected (e.g., an administrator may be presented with a different set of buttons than a normal user). Additionally, a button may be pre-selected for a particular user (e.g., the one of the buttons may be selected upon startup of the system).

Function modes may be selected using function bar 708. Each function mode may have a default display assigned, and the active function mode may be changed at any time using function buttons of function bar 708.

According to an exemplary embodiment, a “dashboard” function mode may provide a single display and may be a collection of workspace views grouped together for a user as a “home page”. According to one exemplary embodiment, the dashboard function mode may be configured to be a default or start-up mode, designated as the active mode upon start-up of the user interface system. The definition and content of the mode may be configured by an administrator or other authorized user of the user interface, according to one exemplary embodiment. The dashboard function mode may provide a layout consisting of one or multiple workspace views.

A dashboard definition may be applied by the user interface to determine the content of the display in the workspace area of the user interface when the dashboard function is active. The dashboard definition may comprise information such as view type, view context, sort settings, component-specific information, which dashboard information is to be viewed in for dashboard layouts with multiple areas, etc. The dashboard view provided by the dashboard function mode may be altered based upon a user selection (e.g., if a user selects an option that results in a new workspace view, the new view is updated in the dashboard function mode).

The alerts function mode may provide workspace views that contain information and provide access to tasks relating to detecting and managing alerts within the facility system. According to one exemplary embodiment, views such as alert summaries may be provided to inform a user of an alert, and/or displays that correlate alerts with potential user actions that may be taken within the system may be provided.

Alert summaries may provide the user of the user interface with alerts that the user is authorized to be provided (e.g., administrators may receive alerts that regular users do not). The summaries may include key information and details of the alert. The summaries may be filtered based on the current selection tree, alert time, or other property if desired, according to an exemplary embodiment. The summaries may additionally provide tasks to a user with tasks relating to responding to the alert. For example, alerts may be viewed, acknowledged, discarded or ignored, etc., and multiple alerts may be managed simultaneously.

The summary function mode may provide workspace views relating to general summary information and provide access to tasks relating to monitoring and managing the operation of the facility system. Summaries may be provided for a workplace, for particular devices and components (e.g., a device summary), for all devices and components (e.g., a “standard summary”), for control systems, etc. Additionally, a user may be able to generate specific views relating to specific criteria provided by the user.

As an example, a standard summary may be provided to the user relating to all facility system items (e.g., devices) that are associated with the current selection made by the user. The summary may include key information relating to each item. The standard summary view may include a method for a user to perform various tasks relating to each item. For example, items may be viewed, values of the item may be changed or altered, and a device summary of the item may be generated and provided. Multiple items may be managed simultaneously.

The device summary that may be displayed via the standard summary may provide a list of facility system items that belong to a selected field device. The device summary may otherwise contain the same information as a standard summary, according to an exemplary embodiment.

The scheduling function mode may provide workspace views relating to providing information and access to tasks related to scheduling features of the facility system. Types of views produced by the scheduling function may include a schedule summary or schedule details view, a view that shows one or more schedules' projected values for a future date, a view that allows a user to modify scheduled events, etc.

A schedule summary view may be provided by the scheduling function mode. The schedule summary may list and provide relevant information for all scheduled items associated with a current selection. The schedule summary may include a method for performing the tasks of viewing the schedules, temporarily overriding a schedule, and displaying details (e.g., a task) relating to the schedule. Multiple schedules may be managed simultaneously.

A schedule details view may also be provided by the scheduling function mode relating to details for a single schedule item. The detailed information may include scheduled items, temporary overrides, projected values, and the schedule's effective period. Tasks relating to the schedule details view may include viewing the details, providing or removing a temporary override, etc. Multiple schedule details may be managed simultaneously.

The diagnostics function mode may provide workspace views relating to diagnostic information and providing access to tasks needed to monitor and evaluate the performance of the facility system. The views may be related to providing trend summaries and trend details, providing “live” data sampling, providing graphical views of display system performance indicators (e.g., providing a view that simply illustrates system performance of a particular system as good, average, or bad), providing “trend study” information, etc.

A trend summary view may be provided for trends configured for items and devices associated with the facility system. The trend summary view may include a view of the list of trends and details regarding a single trend. Trends may be enabled or disabled and multiple trends may be managed and/or viewed simultaneously.

A trend details view may also be provided relating to details for a single trend item and a display of data samples collected by the trend. Trend details may be provided in various types of views (e.g., charts, tables, graphical views, etc.). For example, in a graphical format, the data sampled may be plotted in a chart of values versus time. The data samples may be stored in a historical database. Multiple trend details may be viewed and/or managed simultaneously.

The tools function mode may provide workspace views relating to providing a user with access to information and utility tasks related to the facility system and user interface system. According to one exemplary embodiment, the mode may be restricted to authorized personnel only (e.g., an administrator). A system administration view may be provided by the mode, allowing the user to start and run an update process for the user interface and/or facility system, among other management tasks.

Referring to FIG. 8, a GUI 800 for display on a handheld device is shown, according to an exemplary embodiment. A handheld display may include a header 802 and a workspace area 808. GUI 800 may be configured to accommodate various browser screen resolutions of the handheld device.

Header 802 is shown to include branding logo 803 and function bar 804. Branding logo 803 may be any identifier, symbol, etc., and may be text-based, graphical based, or any other type of display. Function bar 804 may have similar functionality to function bar 708 of FIG. 7. Function bar 804 may contain more or less buttons than function bar 708, based on the window size of the handheld device and other properties. According to one exemplary embodiment, function bar 804 includes buttons for function modes such as alerts, summaries, and schedules. Header 802 may additionally include other information relating to general usage of the user interface and/or handheld device. Workspace area 808 includes scroll bar 809 for navigation, and may be similar to workspace area 706 of FIG. 7 in terms of functionality.

Task Focused User Interface

Referring to FIG. 9A, a graphical user interface is shown, according to an exemplary embodiment. The user interface system includes function bar 708, workspace area 706, and selection area 704 as described in FIG. 7.

Function bar 708 includes multiple symbols and indicators for various function modes that may be accessed. For example, in FIG. 9A, a button 920 for a summary mode is shown as highlighted, indicating that the summary mode is the current active mode of the user interface system.

Workspace area 706 may be configured differently based upon the function mode currently selected by a user of the user interface system. For example, for a summary mode, three columns may be shown. According to various exemplary embodiments, the summary mode may include more or less information, rows, and columns.

Selection area 704 displays a selection tree relating to various facility spaces from which information may be viewed. For example, the row 922 for “Library” is highlighted, indicating that the current selection relates to a “Library” space in the facility. Workspace area 706 may display summary information about the “Library” space as a result. The “Library” space may define the context for the items to be displayed in workspace area 706. In other words, the UI server includes logic for generating a workspace area 706 that only includes items relating to the selected context (e.g., the “Library”).

One column in the workspace area may be labeled “Item” and may relate to providing the name or other identification of any of the items determined to be displayed in workspace area 706. For example, item 902 is labeled “SF-C” (“supply fan command”), which may be an item name or symbol relating to a supply fan control of the BAS. Another column may be labeled “Value” and may relate to a present value associated with each item. For example, the value may be a numerical value, a percentage, a binary or Boolean value, a string, a temperature, etc., depending on the item type and/or particular item. Value 904 is illustrated as “off” and may represent that item 902 is currently in the off state. One column is labeled “Status” and may relate to status information regarding each item. In FIG. 9A, two items are shown as having a “High Alarm” status indicating potential problems determined by computer logic. For example, computer logic may have determined that the sensed temperatures of items AI-3 and OA-T have varied in a significant way from desired setpoints. The values of the associated items are shown as shaded, providing a user with an additional visual warning. Various colors and shading may be used to identify the items and values (e.g., the color “red” may be used to indicate warnings, the color “orange” may indicate values that have been overridden, the color “black” may indicate items that are offline, etc.), or various other identification techniques may be used.

According to an exemplary embodiment, the UI server is configured to display UI elements for initiating tasks directly with the display of items. For example, underlined values (e.g., value 904) may be hyperlinks or other active UI elements configured to initiate a task relating to the item. Advantageously, using this configuration, a user of the graphical user interface may initiate a task from the same workspace area 706 that he or she may be reviewing for other reasons. It is important to note that not every item and/or value includes an associated task that may be initiated via a UI element.

Referring to FIG. 9B, a view of a form display 950 that may be generated when the UI element associated with value 904 of FIG. 9A is activated (e.g., clicked, double clicked, etc.) by a user, according to an exemplary embodiment. Using form display 950, a user may be able to change the value for “SF-C,” for example. The UI element associated with value 904 may be configured to initiate a task to change a value when activated. Display 950 may be a pop-up form, a new page, a new screen, or some other graphical user interface for displaying the elements shown in FIG. 9A. Advantageously, form display 950 provides plain text instructions for changing the value, identifies the item, and allows the user to select the type of change using UI control 908 and to select the new value using UI control 910.

Referring to FIG. 9C, a view of an updated user interface system of FIG. 9A, after the form of FIG. 9B is submitted, is shown, according to an exemplary embodiment. Using form display 950 of FIG. 9B, the value of item 902 is shown as changed to “On”. Value 904 is also illustrated as being highlighted, indicating a change. In addition, status 906 has also changed to “Operator Override” to indicate a change in status based on the change made using form display 950 of FIG. 9B.

Referring generally to FIGS. 10A-10D, another task sequence is illustrated, according to an exemplary embodiment.

Referring first to FIG. 10A, a view of a graphical user interface system is shown, according to an exemplary embodiment. In the illustration of FIG. 10A, the button 1010 for the schedule function mode on function bar 708 is highlighted, indicating that workspace area 706 is configured to display the schedule function mode of the user interface system. The selected context (e.g., indicated by the highlighted row 1012 of the selection tree) is “Floor 2” of “GR Elementary” of a “School District”.

Workspace area 706 is shown to include schedule items determined to relate to the context. Each schedule item may relate to a scheduled event or macro that is stored in the BAS site director. For example, a user may define and store an “Occupancy” schedule. The “Occupancy” schedule may define how BAS setpoints are adjusted according to an expected occupancy schedule for a building space (e.g., “Floor 2”). As the value is listed as “Release,” the graphical user interface indicates that the “OCC Schedule” is not currently active or in control of its scheduled items. Logic in the UI server may determine that the user is authorized to change the schedule so that it is controlling. In order to change the schedule so that it is controlling BAS device activity, the user may select (e.g., click, double click, etc.) a UI element associated with value 1002 (e.g., a hyperlink), which is linked to a task to add a temporary override to the system.

Referring to FIG. 10B, when a UI element associated with value 1002 of FIG. 10A is activated, a form display 1050 may be generated and displayed, according to an exemplary embodiment. Form display 1050 may include the ability to change the schedule's controlling value and to specify a time frame during which the value should be in effect.

Referring now to FIG. 10C, a view of an updated user interface system of FIG. 10A is shown, according to an exemplary embodiment. The UI element associated with value 1002 is used to change value 1002 to an “On” state as a result of a change made via form display 1050 of FIG. 10B. A user may select (e.g., click, double click, etc.) item 1004 to access a view schedule details task.

Referring to FIG. 10D, another view of a user interface system is shown, according to an exemplary embodiment. Workspace area 706 shows a schedule details view that may be selected from the workspace of FIG. 10A or FIG. 10C by activating the UI element associated with item 1004. The schedule details view may provide detailed information regarding an individual schedule for an individual item.

Referring generally to FIGS. 9A-10D, the various values, states, and other data provided in workspace area 706 may be changed in various ways. According to one exemplary embodiment, the data may be static (e.g., the data does not update once displayed unless a user operates a user control of the UI). According to another exemplary embodiment, item data may update and refresh without a user input. The UI server may synchronize with the BAS site director at a regular frequency, and may provide the UI with an update. The update may provide changed data for particular items only, or the update may provide all data for all items and the UI may use logic to determine data to update in workspace area 706.

According to yet another exemplary embodiment, the BAS site director and/or UI server may detect changes within the facility regarding data for an item. Upon detection, the BAS site director and/or UI server may “push” the data to the UI server, and an application on the UI server may trigger an update process with the UI such that the data provided on workspace area 706 is updated.

Referring to FIG. 11A, a flow diagram of a method 1100 of generating a graphical user interface is shown, according to an exemplary embodiment. A UI command is received to generate a view for display for a user (step 1102). Based upon the command, the context and content of the view may be determined (step 1104). The context may be a building space, device, and/or a collection of related items that the user may wish to be displayed on the user interface. The context may be set based on user selections from a selection tree. The content is information related to the context that is displayed. The content may include items such as schedules, BAS device controllers, BAS devices, or the like.

Tasks relating to the content are determined (step 1106). A view is generated for a user or client of the user interface for display (step 1108) such that a user may view, change, or otherwise manage the tasks. The view may include user interface elements for the tasks of the content.

Referring to FIG. 11B, a more detailed flow diagram of a method 1150 of generating a display for a user of the user interface is shown, according to an exemplary embodiment. A UI command is received to generate a view for display for a user (step 1152). The view may be related to a function (e.g., a top level function) of the facility.

The function selected by the user is determined by the system (step 1154). Based upon the selected function, the current task view for the function may be determined by the system (step 1156). The current task view may relate to the view provided in the workspace area of the user interface system. The user context may be determined (step 1158). The user context may relate to a building space, device, and/or a collection of related items that the user may wish to be displayed on the user interface. The user context may be comprised of multiple items (e.g., devices, controllers, sensors, etc.).

Each item of the user context is determined (step 1160). For each item of the user context, filter criteria is determined (step 1162). Filter criteria may be user defined or system defined. Filter criteria may be used to determine if an item should be displayed in the user interface or what properties or components of the item should be displayed.

Each item associated with the user context may have one or more tasks associated with the item (step 1164). For each possible task, a determination is made as to whether the task is applicable or supported by the facility (step 1166) and as to whether the task is authorized to be performed for the current user of the user interface (step 1168). If the steps indicate that the task is not applicable, supported, or authorized for the current user, the task is skipped and the next task is found. Otherwise, the task may be provided to the user of the user interface (step 1170) such that the task may be performed if desired by the user.

Once all tasks are provided or rejected for an item, the next item associated with the user context is determined (step 1172). Once all tasks for all items associated with the user context have been analyzed, a view may be generated on the user interface (step 1174). The view may include all applicable items associated with the user context, including all associated tasks for each applicable item.

Filter Based Activity

According to an exemplary embodiment, workspace area 706 of FIG. 7 may provide a list of all items of a building space or other context. According to another exemplary embodiment, systems and methods to allow a user to filter through all the items to display for a given function and/or context are provided. In other words, a mechanism for allowing a user to define data filters is provided. The data filters result in only a certain selection of items being shown in workspace area 706. For example, a user may be able to filter for a subset of items within a building space, and the result of the search may be provided in workspace area 706, instead of workspace area 706 listing all items within the building space or other context.

According to an exemplary embodiment, filters are created by building a filter definition. A filter definition defines the data to be displayed (in workspace area 706) in the context of a selected building space, user view folder, or other context. A filter definition may be pre-defined by a site administrator or created and/or edited by a user. Pre-stored or created filter definitions may be accessed and/or applied by the user via any number of methods (e.g., filters may be applied via a button press, a custom item on the selection tree, a pop-up menu, a “hot key,” or otherwise). According to an exemplary embodiment, filter definitions may be accessible via a folder with a fixed location within the selection component of the user interface. Some filter definitions may apply to any type of function view and/or context. Other filter definitions may be configured to only effect a subset of building spaces or user-defined contexts. One or more filter definitions may be associated with a building space, user view folder, or other context. Furthermore, a single filter definition may be associated with multiple building spaces, user view folders, and/or other contexts.

Filter definitions may be applied to various contexts. For example, a filter definition may be applied to a building space (e.g., a library) and the resulting view in workspace area 706 may relate to the filter definition. If a filter definition does not exist for a particular context, a default view may be provided. Multiple filter definitions may be used for a single context. The filter definition may be adjusted for the type of user interface used (e.g., a UI for a PC may be able to display more details than a UI for a handheld device; therefore, the filter definition may be altered if a handheld device is being used).

Referring now to FIG. 12A, a view of a user interface 1200 for configuring filter definitions is shown, according to an exemplary embodiment. UI 1200 may display (e.g., pop-up) when a user activates a UI element to create a filter definition. According to an exemplary embodiment, a workstation system (e.g., workstation UI/BAS SCT 414 shown in FIG. 4) may be used to generate user interfaces for configuring filter definitions. According to yet other exemplary embodiments, user interfaces for configuring filter definitions may be generated by the UI Server, the workstation UI, or the UI server and the workstation UI. While a variety of user interfaces for building a filter definition may be provided, a row and column based method is provided according to various exemplary embodiments. Such a method may advantageously be intuitive for users given the row and column based output that the application of the filter definition may provide.

Users may begin building a filter definition by creating a row definition. Creating a row definition includes selecting to include certain item requirements (e.g., via control 1202) and/or criteria requirements (e.g., via control 1204) beyond the basic item requirements. For example, as shown in FIG. 12A, the user has selected to require the items to meet the “field controller” requirement. The user has also selected that the items include a name having “VAV” or “FEC” as the first three letters. Further, the user has selected that the field controller be associated with a HVAC and that the reference field for the item contains the string “FEC” or “VAV”.

After a row definition is created, a user may continue building a filter definition by then creating a column definition. An exemplary user interface 1250 is shown in FIG. 12B for creating the column definition. Column definitions may be used for further filtering (e.g., excluding of items) or may be used to format and/or select item attributes for display in the results. A user may define a column label (e.g., using control 1252) followed by criteria (e.g. using control 1254) that information displayed in the column must meet in order to be displayed.

Referring yet further to FIG. 12B, columns may be added by clicking button 1256 and removed by clicking button 1258. During creation and/or editing of a filter, definition panel 1260 is updated that displays the presently selected row and/or column criteria of the filter. According to an exemplary embodiment items on definition panel 1260 may not be directly edited but may be selected (e.g., clicked) and then edited using controls such as 1252 and 1254. According to other exemplary embodiments, information on the definition panel is directly editable.

Once created and/or edited, the filter definition may be saved via button 1262 or via another method. Filter definitions may be saved for a user and stored in memory of the UI server and/or saved to the site director and periodically synchronized with the site director. Once saved, filter definitions may be applied to selected contexts. An exemplary view of a result screen 1280 is shown in FIG. 12C. Workspace area 706 is shown to include a result area 1284 and an additional information area 1282. Additional information area 1282 may display information falling outside of the filter definition but nevertheless desired to be viewed on the same screen as the results by the user. According to an exemplary embodiment, one or more user interface screens (e.g., pop-ups) may be provided for a user to create an additional information definition that will be associated with one or more filter definitions. In the example shown in FIG. 12C, the user has elected to display the name of the site shown relating to the search results and/or selected in the selection tree. It is important to note that the results need not be displayed in a traditional row column format, but may be tiled (as shown in FIG. 12C) or displayed in some other manner.

Referring generally to FIGS. 12A and 12B, the method of configuring filter definitions may use any type of logic to determine qualifying items based upon the configured filter definitions. For example, in FIG. 12A, the same item (“Name”) is shown as accepting two different strings as a valid input. The logic for the filter definition may use a logical OR statement to find all such names that contain either the string “VAV” or “FEC”. Once all like items are logically OR'd together as a group, different items may be joined together using a logical AND statement to find all valid items that fit the criteria specified by the user. For example, items that have either the string “VAV” or “FEC” in the “Name” of the item may be logically AND'd together with all items which “Object Category” equals “HVAC”.

Referring now to FIG. 13A, a method 1300 is shown for establishing a filter definition that may be used by a UI server (or other component) to filter items to be displayed on a building automation system graphical user interface provided to a client device and for interaction by a user. Method 1300 includes generating a computer based form (e.g., a form shown in FIGS. 12A and/or 12B, a pop-up window, a new screen, a new page, etc.) for allowing a user to enter filter criteria (step 1302). Once the filter criteria is received via the computer form, a filter definition may be created using received filter criteria (step 1304). The filter definition may include a table of filter values, a query string (e.g., a structured query language (SQL) string), object code, computer code, a markup language file (e.g., an extensible markup language file), or another data structure suitable for defining a query or filter. The created filter may then be saved to memory (step 1306). The filter may be saved to a memory associated with the UI server and/or memory associated with the site director. According to an exemplary embodiment, the filter is primarily stored and retained in the site director.

Referring now to FIG. 13B, a further method 1350 for generating the graphical user interface view is shown, according to an exemplary embodiment. The method may supplement FIG. 13A and/or the steps of 13B may be integrated into or between various steps of FIG. 13A. Method 1350 includes providing an interface to associate a filter with a selected building space (step 1352). Method 1350 may further include relating the saved filter to the selected building space (step 1354) and saving the association (e.g., in a text file, relational database, or another data structure). It is important to note that a plurality of building spaces may be associated with the saved filter (e.g., step 1356). Associating multiple building spaces with a filter may be accomplished by copying the filter to and associating the copy with a building space (e.g., by specifically naming the copied filter, by placing the copy of the filter in a folder or other memory location associated with the second building space, by using a relational database, by using a flat text file, or by using any other suitable data structure). Additionally, the same filter may be associated and/or linked to multiple building spaces without copying the filter, allowing a single change to the filter to be applied to all building spaces associated with the filter. Method 1350 may further include providing an interface for allowing the user to choose between automatic application of the filter definition and a standard summary associated with the building space (step 1358). Step 1358 may allow the user to set a “new” default screen or view for a function mode, context, and/or building space. This may advantageously allow the user to initially view only those items he or she is most interested in, rather than all items associated with a function mode, context, and/or building space. The decision regarding the default filter and/or standard summary may be stored in a user profile, a configuration file relating to the user, another configuration file, or another suitable data structure. According to an exemplary embodiment, the system is further configured to copy the filter definition to a first profile (or other configuration file) associated with a first user and a second profile associated with a second user (step 1360). The administrator may be the only user able to conduct such copying or the user may be able to copy his or her created filter definitions to other users' profiles. This feature may advantageously allow users of a building automation system to collaboratively increase the efficiency of the users' experience.

Referring further to FIG. 13B, associating filters with spaces and/or users may include associating a filter with a folder or node of a selection tree. According to an exemplary embodiment, once associated with a folder or node, selecting or activating the filter will include and filter items in subfolders of the folder. According to other exemplary embodiments, the subfolders' folders will also be included in the search and filtered.

Referring now to FIG. 13C, a flow diagram of a method 1380 of a UI server using a filter definition to provide a GUI for a user is shown, according to an exemplary embodiment. According to another exemplary embodiment, the GUI itself may use the filter definition to provide a GUI for a user. The saved filter definition (e.g., the filter definition saved in step 1306 of FIG. 13A) may be applied (step 1382) to a set of building automation system data items. The application may occur, for example, after a user selects a new context that has been associated with the filter, after the user selects the filter for application to a context, after the user selects a new function mode, when a user selects a filter definition, or by any other number of triggering acts. Once applied (manually or dynamically) a graphical user interface or user interface view/area may be generated and provided to the UI, including the results of the applied filter definition (step 1384). The look of the results may approximate that shown in the other Figures or otherwise. The application of a filter definition may include querying a data store and/or site director in a certain way. Alternatively, a complete set of data may be provided from the data store and/or site director and the filter may suppress which results are displayed to the user.

According to an alternative exemplary embodiment, a method of filtering items may be provided in workspace area 706 or elsewhere on the UI such that a user may filter through items or other objects of the facility without navigating through the screens illustrated in FIGS. 12A and 12B, for example. Such a method may allow for dynamic filtering of items listed in workspace area 706. One or more UI controls may be provided on workspace area 706 and/or on another portion of the UI. A user may operate a control, indicating a change in filter preference or otherwise. The list of item in workspace area 706 may dynamically change, updating the list of items provided in “real time”. For example, a UI control such as a drop down box may be provided, the drop down box including a list of item types. Upon selection of an item type, the system may exclude all items not being of the selected item type for display.

While the exemplary embodiments illustrated in the figures and described herein are presently preferred, it should be understood that the embodiments are offered by way of example only. Accordingly, the present application is not limited to a particular embodiment, but extends to various modifications that nevertheless fall within the scope of the appended claims.

The present application contemplates methods, systems and products on any machine-readable media for accomplishing various operations. The embodiments of the present application may be implemented using existing computer processors, or by a special purpose computer processor for an appropriate system, incorporated for this or another purpose or by a hardwired system.

It is important to note that the construction and arrangement of the interface components or hardware components as shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages. For example, elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. Accordingly, all such modifications are intended to be included within the scope of the present application. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. In the claims, any means-plus-function clause is intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present application.

Embodiments within the scope of the present application include program products comprising machine-readable media for carrying or having machine executable instructions or data structures stored thereon. Such machine-readable media can be any available media that can be accessed by a general purpose or special purpose computer or other machine with a processor. By way of example, such machine readable media can comprise RAM, ROM, EPROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code in the form of machine-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer or other machine with a processor. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a machine, the machine properly views the connection as a machine-readable medium. Thus, any such connection is properly termed a machine-readable medium. Combinations of the above are also included within the scope of machine-readable media. Machine-executable instructions comprise, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing machines to perform a certain function or group of functions.

It should be noted that although the figures may show a specific order of method steps, it is understood that the order of the steps may differ from what is depicted. Also two or more steps may be performed concurrently or with partial concurrence. Such variation will depend on the software and hardware systems chosen and on designer choice. All such variations are within the scope of the application. Likewise, software implementations could be accomplished with standard programming techniques with rule based logic and other logic to accomplish the various connection steps, processing steps, comparison steps and decision steps.
